Abstract
A method is described for purifying plasmid DNA from a mixture containing plasmid DNA and genomic DNA. A solution containing both plasmid DNA and genomic DNA is treated with at least 80% by weight saturation ammonium sulfate, thereby precipitating the genomic DNA and providing purified plasmid DNA in solution. Genomic DNA levels in the purified plasmid DNA product are less than 1% by weight based on the plasmid DNA. The purified plasmid DNA is suitable for use in humans.
